Introduction
Friction is a part of our everyday life. Nearly every movement we make involves friction, and we have instinctively learned to take advantage of friction, or the lack of friction, since our childhood. Simple devices that rely on friction are everywhere around us. This workshop will help you see and appreciate the role of friction. As we study friction, lets also think about the differences between what scientists do and what engineers do. Scientists and engineers have been studying friction and its effects for a very long time. Engineers in particular have a real "love-hate" relationship with friction. For many jobs, an engineer must fight against friction and its effects through careful, clever design. In this workshop, we'll talk about the wedge and the wheel -- the ancient engineers' tremendously successful approach to friction. Roughly speaking, the scientist's role is to understand friction, what causes it and how those causes can be controlled. The engineer's role is to anticipate friction's part in the task at hand, and to use friction to the best advantage in the design of materials, machines, and experiments.
In this workshop, you will be a scientist, doing experiments to learn about friction and thinking about how it works; and then you will be an engineer when you
